e SIMs with iPhone 13 - messed up functionality with primary SIM

Hi, I’ve been using e SIMs when I’m traveling from Airalo since I got new iPhone 13 in January. After using one from Canada, deleting it when I was finished and returning to my home country and activating my physical SIM, I’m having major issues. Phone is constantly in and out of service, switching constantly from 5G to 3G (it’s never gone to 3G before, ever). I cannot connect half the time and everyone else’s connectivity that I’m with is fine, also on the same mobile network. Switching off cellular or going into airplane mode does nothing. Switching the phone off and back on seems to temporarily trigger the network back, but only for a short time. It’s baffling and I’m convinced the e SIMS have messed up my phone. Have contacted Airalo 3 times for support and no response. All settings under Cellular seem to be normal / the same as before I used the e SIM. Did anyone else have this problem? Any ideas to resolve this?

Thank you.

iPhone 13, iOS 15

To use two different carriers, your iPhone must be unlocked. Otherwise, both plans must be from the same carrier. If a CDMA carrier provides your first SIM, your second SIM won't support CDMA. Contact your carrier for more information. 


If you have an enterprise or corporate cellular service plan, check with your company administrator to see if they support this feature.
